I'm a total newb here, but I'd guess a coil pack as the numbers are indicating misfire in cylinders 7-12?
there is a place that has updated/improved the coil design- I don't know if we are allowed to share links? look for v12icpack- they even let you rent a coilpack to determine if that's the cause.

I've been thru this a few times. Once it was the coil pack the other time it was the Voltage Transformer that sits atop the engine. I replaced them via v12icpack. Clark was very cool, knowledgeable and accessible. I would advise you to do all the following prior: Check/replace the 02 sensors. They can assist in misfire codes. A spark plug change...all 24 of them! Make sure they are the proper NGK plugs. Only OEM will do. Check for valve cover gasket leaks. Oil dripping into one of the spark plug passages can cause issues. When you remove the coil packs, check the red boots on them. A bad or missing boot can cause problems. After exhausting all those issues, rent the coil and VT from Clark. The parts are an upgrade of what MB sells and comes with a nice warranty. It seems like a lot to do but your car will purr like a kitten for a LONG time to come! Good luck!
